What is DevOps (In my words):

• A cross-functional mindset that makes your team more agile

• The practice/culture to remove the barrier between developers (who develop apps, write code, are responsible for implementing feature requests, bug fixes, etc.) and operators (who deploy those apps, manage IT infrastructure/servers, and are responsible for uptime, security, stability, scalability, etc.)

• Collaboration between operators, system administrators, DB administrators, developers, testers, etc.

  • DevOps Focus Areas:

    1. 🎯 Reduce Organization Silos
       Collaborate, communicate, educate and share.

    2. 🚀 Push Gradual Changes
       Roll out small changes so that if something goes wrong you can easily roll back to a previously (acceptable) state.

    3. 🐞Embrace Failure
       Wherever a human element is involved, failure is inevitable. A good DevOps strategy is one that considers failure as a normal thing.

    4. 📊Monitor Everything
       Monitor everything, generate meaningful data, analyze it and reduce toil over a period of time.

    5. 🤖Tooling & Automation
       Leverage tools to implement IaC and CI/CDIt's not necessary to learn all available tools/services in each category, and new tools can be discovered along the way. Focus on the ones that are needed in your workflow or the ones your potential employer/client is using.

       Keep learning and experimenting with new tools and technologies, but make sure your basics are strong.

Hence try to follow a Technical roadmap to becoming a DevOps engineer. The roadmap can include the following steps:

• Learn a programming language: In addition to scripting, it's helpful to know at least one programming language such as Python, Ruby, or Go. This will allow you to write more complex automation scripts and applications that integrate with DevOps tools.

• Familiarize yourself with version control using Git.

• Get comfortable with Linux/Unix/Posix-compliant operating systems.

• Learn the basics of computer networking.

• Learn containerization using tools like Docker, Podman, or CRI-o.

• Learn container orchestration using tools like Docker Swarm, Kubernetes, or Mesos.

• Familiarize yourself with cloud platforms like AWS, Azure, or GCP.

• Learn continuous integration/continuous deployment/continuous delivery (CI/CD) using tools like CircleCI, Github Actions, or Jenkins.

• Learn infrastructure as code (IaC) using tools like Terraform, Pulumi, or Ansible.

• Learn logging and monitoring using tools like Grafana and Prometheus.

  The DevOps landscape is constantly evolving, so it's important to stay up-to-date on new tools and best practices. Make continuous learning a part of your DevOps roadmap by attending conferences, webinars, and online courses, and reading industry blogs and articles.
